I am surprised no one has suggested your source is a weak link. I am a firm believer in the "garbage in is garbage out" in audio.
I am not familiar with the Auralic Aries Mini but my internet search suggests it is dated and was never an audiophile component when it was new.
I missed your price point in the discussions, I have an Innuos streamer and love it and the Sense app, but I know their entry products are getting expensive.
A new or used streamer is where I would look to upgrade your system. If you can afford an Innuos or something similar I think it would punch the ticket for you.
